last year i blew a head gasket on my boosted d16z. tore the engine apart and replaced it (oem honda, arp headstuds, del sol radiator, had the head milled) ran perfect all last year and the begining of this year, just the other day on my way home driving up my big mountain car started to heat up. now whenever i boost the temp gauge goes up.. unless my heat is on then it stays cool as can be. the oil looks fine. and ive tried to let it run without the cap on till the fan turned on ( took forever ). so i figured i would ask the pros what they thought.... head gasket again.... block warped.... im only running about 6lbs... compression test showed 195 across the board

are you losing coolant? air bubbles? is the thermostat working? any smoke?

 

not loseing any coolant, bled all the air out, not smoking at all, from waht i can tell the thermostat opens(bottom hose gets warm) and the fan kicks on but only for a few seconds even when its hot...

 

i had the same problem sorta. i have a z6 in my car i replaced the headgasket and added ARP studs and it was fine but i stopped drving it for a couple weeks and i took it out one day and it started running hot for no apprent reason. took it out again a few weeks ago and it was fine.

 

what were u running for engine management? did you have arp studs?

 

i have arp's now and as of now im runnin a crappy fmu.. if i have to do the headgasket it puts my phearable ecu on hold again...

 

did u know what ur a/f's were like? anything to retard the timing? if it was stock timing it coulda been enough to lift the head even @ 6psi. just guessing

 

stock timing.. what are my chances of the block being warped...
